Related Terms

TRAILBOARD

A decorative board at the bow of a vessel, sometimes bearing the vessel's name.

COMPOUND

(1) chemically speaking, a distinct substance formed by the combination of two or more elements in definite proportions by weight and possessing physical and chemical properties different from those of the combining elements. (2) in petroleum processing, generally connotes fatty oils and similar materials foreign to petroleum added to lubricants to impart special properties.

BALL BEARING

An anti-friction rolling type bearing containing rolling elements in the form of balls.

DETERGENT

In lubrication, either an additive or a compounded lubricant having the property of keeping insoluble matter in suspension thus preventing its deposition where it would be harmful. A detergent may also redisperse deposits already formed.

JOURNAL BEARING

A sliding type of bearing having either rotating or oscillatory motion and in conjunction with which a journal operates. In a full or sleeve type journal bearing, the bearing surface is 360° in extent. In a partial bearing, the bearing surface is less than 360° in extent, i.e., 150°, 120°, etc.

BEARING

A support or guide by means of which a moving part such as a shaft or axle is positioned with respect to the other parts of a mechanism.

AERATION

The state of air being suspended in a liquid such as a lubricant or hydraulic fluid.

BLACK OIL

A lubricant containing asphaltic materials, which impart extra adhesiveness, that are used for open gears and steel cables.

ADHESION

The property of a lubricant that causes it to cling or adhere to a solid surface.

False brinelling

False brinelling of needle roller bearings is actually a fretting corrosion of the surface since the rollers are the I.D. of the bearing. Although its appearance is similar to that of brinelling, false brinelling is characterized by attrition of the steel, and the load on the bearing is less than that required to produce the resulting impression. It is the result of a combination of mechanical and chemical action that is not completely understood, and occurs when a small relative motion or vibration is accompanied by some loading, in the presence of oxygen.
